Hello, Proton.

Fair notice: I did allow Lumo to aid my crafting of this feedback and suggestion. I thank you folks for all that you do!

Observation: Following the recent UI update (April 2026), I noticed that Lumo briefly displays a numbered list of internal reasoning steps (e.g., "User is asking X, analyzing data Y") before posting the final response. While this currently disappears quickly, it offers a unique glimpse into the AI's logic.

Insight: Rather than viewing this as a transient artifact, I believe this "reasoning trace" could be a highly desirable feature if made persistent and user-controlled.

Enhanced Trust & Verification: Seeing the logic chain allows users to verify how a conclusion was reached, not just what the conclusion is. This is particularly useful for complex queries, fact-checking, or academic work.
Improved Communication: Even though Lumo often grasps nuance quickly, having the reasoning visible can help users refine their prompts in real-time. If I see Lumo is misinterpreting a premise in the "thought" phase, I can correct it before the final answer is generated.
Educational Value: For users learning about AI or critical thinking, observing the step-by-step breakdown is a powerful learning tool.

Recommendation: I propose adding a "Show Reasoning" toggle in the settings or a button next to the input field.

Option A (Toggle): A permanent setting to keep the reasoning steps visible alongside the final answer (perhaps in a collapsible sidebar or indented block).
Option B (On-Demand): A "Reveal Logic" button that, when clicked after a response, expands the hidden reasoning steps used to generate that specific answer.
Option C (Hybrid): Keep the current brief flash for casual users, but allow power users to "pin" the reasoning view for the duration of a session.

Conclusion: This feature aligns perfectly with Proton's ethos of transparency and user control. By giving users the option to see the "engine room" of the AI, we can foster deeper trust and more effective collaboration. It transforms Lumo from a simple answer engine into a transparent thinking partner.
